Application sled February 2 1, 1882. (Nomad.)

'o all 'whom yit may concern-t y v Be it known that l, JOHN M. FENNERTY, of Memphis, in the county ot' Shelby and ,State of Tennessee, have invented certaiunew and usctnl .improvements in ventilators; and I do herebydeclare that the following is a full, clear,

rend exact description of theinvention, which will enable others skilled in thefart to which it .appertoins to make and use the same, reference .i c

being had to the accompanying drawings,l which form a part of this spec'ication.

, Figure 1 is c vertical sectional view; and Fig.v 2 .is e horizontal or cross sect-ion on the line ar fr, Fig. l. t

Similar letters of reference indicate correeponding parts in both figures.

This inveetiou relates to ventilators; .and it, coneists in certninl improvements in the coustruction of the same, which will be hereinafter fully describedeud particularly pointed out, in the claims.

In the drawings hereto annexed, A reprecents e'i/ertical tube, secured to or provided with n bese o rl ange, B, by which it may be se cured in the desired position. Tube Ais provided about midway of its length 'with an annular ilangedriin, G', from which braces D,

which may be attached lin any suirable umnner, extend downwardly and outwardly, es shown. The tiauged ri'm C forms :t bearing or 'turn-table for n tube, E, encircling the upper end of tube A, and carrying at its upper end o trnnsverse horizontal tube, F, provided at one end with a funnel, G. and at its other end with wings or venes El. The inner end of funnel Gr extends into tube Flaud terlninntee over the upper end oftube E. Y u l g i is a 4vertical rod or spindle, mouuted'in heerings in crosspicces J in tube A, and havs. .ng et its upper end a ring, K, encircling the inner narrow end of yfunnel braced and balanced. The wide front end or mouth of funnel G may' Q, which is thus be covered with wire-nettingL, in order to pref vent. dirt and obstructions from entering the ventilator. g

The operation of my invention will beread- 'ilyuuderstood 'The air entering through funnel G escapes through the tube 1F, thus creating n suction iu the tube A, by which the foul air from the apartments below, with which said tube A is connected, is carried otfthrough vulve h?, tube A, and tube F. A draft in a. downward direction is impossible, because the valve N will instantly close and prevent air from.

passing downward through tnbe'A. Likewise, and forV the same reason, dust and dirt are prevented from entering through the ventilator thenpartment .or apartments Vwith which it is connected. Rain is also thus excluded, and

.a cock or faucet, 0, is provided at the lower end of tubeA for the purpose of enabling water accumulating between said tube and the inverted i'uunel M to be drawn oft'.

Having thus described lnyinveution, I claim and desire to secure by Letters Patent of the United States;- t

l. lThe combination ,of the tube A, having i 'verted funnel M', provided with vulve N, substantially as and for the purpose set forth.

3. In a ventilator constructed substantially as described, the .tube A, having inverted funnel M, provided with vlveN, and the cock or I faucet O, as and for the purpose set forth.

' In testimony that I claim the foregoing :is my own I have hereto aixed my'signature in presence of two witnesses'.
